Now in our blocks for trucks we use the MB91520 series. We want to choose a promising line of microcontrollers for further use in their products. Perhaps you will help orient.
We have the following wishes:
- automotive classification
- the life of not less than 10 years,
- number of legs from 48 (for the youngest in the line) to ~ 200 (for the oldest in the line),
- LQFP package, - power supply (preferably + 5V),
- availability of CAN, for the younger (48 pin) 1 piece min, but preferably 2 pieces, for all the others at least 2 pieces, in the older 4 pieces,
- presence of FPU,
- ADC: at least 12 bit, for older 2 modules and up to a total of 40 channels,
- the presence of SPI channels of at least 5 pieces,
- PWM outputs with dead-time generator with hardware interrupt 6-8 pcs.,
- quadrature counting module 1-2pcs.,
- capture module (for counting inputs) 32-bit minimum 6 pcs.,
- RAM memory: low-end models 128kbyte, high-end models 300kbyte,
- ROM memory: low-end models 256kbytes, high-end models 2048kbytes,
- core frequency of at least 80 MHz for RISC architecture
- availability of a free compiler.
